不锈钢气动三通球阀安装之前的准备工作
  Stainless steel ball valve before the installation of the preparation work is divided into the following steps:
 
  1,cleaning steps:
 
  1)according to the processing requirements,stainless steel valve parts need to do polishing treatment,the surface can not have machining burr,etc.;
 
  2)all spare parts for fat treatment;
 
  3)after completion of degreasing pickling and passivation(detergent without phosphorus);
 
  4)after pickling passivation with pure water rinse clean,can not have pharmaceutical residues(carbon steel parts to save this step);
 
  5)parts one by one surface can not be wired to dry non-woven fabrics,wool and other retained components,or with clean dry nitrogen;
 
  6)use non-woven fabrics or precision filter paper dip analysis of pure alcohol to wipe the parts one by one,until there is no dirty color.
 
  2,assembly requirements
 
  The cleaned parts must be kept in a sealed and kept for installation.The installation process is as follows:
 
  1)installation workshop to ensure clean,or build a temporary clean area(for example,the purchase of new color cloth or plastic film,etc.)to prevent dust entering the installation process.
 
  2)assembly workers must wear clean cotton clothing,wearing a cotton cap,hair can not leak,wearing a clean shoes,wearing plastic gloves(skim).
 
  3)assembly tools must be cleaned before assembly to ensure cleanliness.
 
  3.Other requirements
 
  1)to complete the valve with nitrogen purge at least 1 minutes.
 
  2)air tightness test must be pure nitrogen.
 
  3)airtight test after passing the bag sealing,with a clean polyethylene cap seal,the use of polyethylene cap before the use of organic solvent immersion,wipe clean.
 
  4)and then sealed with vacuum bag.
 
  5)the final packing.
 
  气动不锈钢三通球阀安装前的准备工作分为以下几个步骤:
 
  1,清洗步骤:
 
  1)根据加工要求,不锈钢阀门零件需要做抛光处理,表面不能有加工毛刺等;
 
  2)所有脂肪处理备件;
 
  3)脱脂酸洗和钝化(无磷洗涤剂)完成后;
 
  4)酸洗钝化后用纯水冲洗干净,不能有药物残留(碳钢零件节省这一步);
 
  5)部件一个接一个表面不能接到干燥的无纺布,羊毛和其他保留的部件,或用干净的干燥氮气;
 
  6)使用无纺布或精密滤纸浸泡分析纯酒精,逐一擦拭部件,直到没有脏的颜色。
 
  2,装配要求
 
  清洁的部件必须保持密封,并保持安装。安装过程如下:
 
  1)安装车间确保清洁,或建立临时清洁区(例如购买新颜色布或塑料膜等),防止灰尘进入安装过程。
 
  2)装配工人必须穿干净的棉衣,戴上棉帽,头发不能泄漏,穿干净的鞋,戴上塑料手套(脱脂)。
 
  3)组装工具必须在组装前进行清洁,以确保清洁度。
 
  3.其他要求
 
  1)用氮气吹扫完成阀至少1分钟。
 
  2)气密性试验必须是纯氮气。
 
  3)密封试验后通过袋密封,用干净的聚乙烯盖密封,使用聚乙烯盖前使用有机溶剂浸泡,擦拭干净。
 
  4),然后用真空袋密封。
 
  5)最终包装。
